Whiskey

I have a new addition to the pets. Tuesday night (around 1 am) Connor texted me that he had a present for me. I went to the door (normally I am asleep by then, but I had Wednesday off so I was up. Connor was up because after work he went long boarding with his friends. He was not at the door, so I went back to my room. He came in a minute later with a rat, and was like "I painted one of your rats" I was like that's not one of my rats. They were longboarding, and saw what they thought was garbage. It was a hooded rat. So he brought it home to me, since I have 3 anyways. We named her Whiskey as she is a little wobbly. She seems to have a problem with her left hind area. It does not seem to bother her. She is also named Whiskey because it is in the phonetic alphabet and fits with the other three, She has lice so she is in quarantine in an aquarium for now. Does anyone have any hints on getting rid of lice in rodents?
